A candlestick is a method of plotting prices on a graph or a chart; a single candlestick can show the open, high, low, and closing price of a cryptocurrency in a pre-defined period. Even though it was first used in the 18th century, candlestick charts are used by almost everyone for technical and financial analysis in financial markets.
Candlesticks are colored red and green to indicate a bearish or bullish nature in that given time period. If the price at the time of opening is lower than the price at the time of closing, the candle is of green color, indicating a bullish nature in that time period; also, the inverse is also true.
